Motion triggered LED matrix display

If you are planning to implement any electronic moving display system that is activated by movements in its surroundings then just have a look on the project posted by Jer from Volts and Bytes, where an Atmega8 is used to activate a Sure Electronics 0832 LED matrix display when motion is detected by the attached PIR sensor. Check the link […]

DIY LEDs as light detectors

Embedds admin in his post has perfectly written:  “From semiconductor physics we know that semiconductor junction when exposed to light becomes more conductive. So when LED cathode is connected to +5V and anode to 0V it simply charges as capacitor.Then program switches anode pin to high Z input and read its state. Depending on time taken […]

DIY Candle Simulator

Candle light is usually warm and waves slowly with the random oscillations of the air in the surrounding environment. It should be possible to simulate the effect of a candle with a small electronic circuit that generates random patterns or numbers. Here is a simple such circuit shared by Embedds member. To create the candle effect […]

RGB LED Vehicle Turn Signals

If you have a show car the here is an interesting project for you. You can build your own RGB LED Vehicle Turn Signals that StarfireMX developed for his Ford Mustang. The system used a number of Arduino based controllers and XBee wireless devices to allow remote control of the modes and color selections. Starfiretech […]

DIY Spinning LED Globe

One crazy Spinning LED Globe is constructed by Csaba Bleuer, a friend of Hackedgadgets member Alan Parekh. You can build this project using ATMega Microcontroller and referring to Csaba’s hand drawn schematic. The jaw-drooping display effect is created by a program BmpToAscii. In this project the image is displayed using the ascii code, which gives an effect of rotating globe. To further explain the […]
